COMPOSITION OF MATTER FOR CLEANING AND POLISHING PAINTED 0R VARNISHED SURFACES.

Be it known that I, FREDRICK C. DONO- VAN, a subject of the King of Great Britain,

residing at Vancouver, in the Province of British Columbia, Dominion of Canada, have invented a new and useful Composition of Matter for Cleaning and Polishing Painted or Varnished Surfaces, of which the following is a specification.

My invention relates to polishes and cleaners and has for its object the production of a Composition of matter which will resurface and renew paints, varnishes, and enamels, such as are commonly used on automobiles, furniture, interiors, and the like. Such surfaces, and particularly automobiles, are exposed to the action of the elements, and are sometimes cleaned with acids or alkalis. All of this tends to dull. the luster of the finished surface and renders the objects unsightly. These, surfaces are originally produced by the repeated applications of thin coats of filler or varnish, these coats being repeatedly rubbed down with pumice stone or the like. When they become dulled by use it is common practice to add subsequent coats which is not entirely satisfactory as to results, and which is expensive and requires a considerable time.

With my invention I resurface and renew the original finish at a fraction of the expense and in a fraction of the time required for repainting and revarnishing.

My compound consists of a polishing material, such as tripoli or the like, carried in a suitable vehicle, such as linseed oil, together with a solvent such as turpentine. For the purpose of filling cracks in the surface a smallamount of shellac dissolved in alcohol may be used.

I find that tripoli is a very satisfactory polishing material but other similar materials may be used if desired. In the same manner, while I use boiled linseed oil, there are a number of similar materials, which givegood results. While I use turpentine there are other solvents used by painters which give nearly as good results, and while I prefer pure shellac gum mixed with alcohol as my fourth ingredient this may be left out or a similar gum may be used.

Specification of Letters Patent.

Patented Jan. 5, 1915..

Application filed March 25, 1913. Serial No. 756,808.

While I give in this specification a preferred. formula I wish the doctrine of equivalents to be broadly applied as briefly outlined above.

My invention therefore consists broadlyefiiciency and the above is given merely as a formula that I have found to work well in practlce.

The method of operation in cleaning any object, for example, an automobile, using my composition of matter is as follows: A piece of soft cheese cloth or old turkish toweling is saturated with water and a small amount of water is thrown upon the surface to be cleaned. A small portion of the composition is then put upon the cloth and the surface is rubbed therewith. No preliminary washing is necessary. The various ingredients form an emulsion which takes a pasty form, the vehicle and the solvent loosening the grease and dirt which is also cut by the polishing material. The polishing material acts upon the roughened surface of the old paint giving it a high polish. After going over the surface it is washed with clear water, without soap, and the surface is left in a hard highly polished condition. I have found that even on new automobiles that have never been used or washed that my composition of matter greatly enhances the polish and I have repeatedly so applied it.

The small portion of shellac that I use serves to fill up minor scratches and indentations and to give a thin film of new material over the entire surface treated.

My invention should not be confused with either soaps or the so-called furniture polishes. to produce a composition that is not alkaline and the action is that of a soap. On the other hand furniture polishes are generally strongly acid. Either acids or alkalis have a destructive action on highly polished surfaces and my composition of matter which is entirely neutral is absolutely harmless to such surfaces.

. I claim as my invention:

1. A composition of matter in the form of a liquid adapted to form an emulsion with Water comprising a polishing abrasive, a neutral vehicle for said abrasive, and a solvent, substantially in the proportions described.

' 2. A composition of matter in the form of a liquid adapted to form an emulsion with Water comprising a polishing abrasive, a neutral vehicle for said abrasive, a small portion of resinous gum dissolved in alcohol,

.and a solvent, substantially in the proporresinous gum dissolved in alcohol, boiled linseed oil,'and spirits of turpentine substantially in the proportions described.

5. A composition of matter for cleaning and polishing painted, varnished, or enameled surfaces, comprising tripoli, eight ounces; boiled linseed oil, three gallons; and spirits of turpentine, two gallons.

6. A composition of matter for cleaning and polishing painted, varnished, or enameled surfaces, comprising tripoli, eight ounces; boiled linseed oil, three gallons; spirits of turpentine, two gallons; and shellac in alcohol, four ounces.

7. A composition of matter in the form of a liquid adapted to form an emulsion With water, comprising tripoli, shellac in alcohol, boiled linseed 011, and spirits of turpentine, substantially in the proportions described.
